Synopsis An anchorage test programme carried out on the site of deep basement construction in Norwich, UK, allowed determination of anchorage capacities, creep characteristic data and the exhumation of several anchor bodies in chalk. This paper reports on the performance of the chalk based anchorages, the observation of exhumed grout body shapes and sizes, extent of grout penetration into disso...

This paper addresses the problem of quantifying the mechanical contribution of rockbolts installed systematically around tunnels (regularly spaced around the tunnel) excavated in rock masses. Assuming that the mechanical contribution of grouted rockbolts is that of increasing internal pressure within a broken rock mass, a new procedure for computation of ground response curves for a circular tu...

A novel precast concrete beam connected using double-grouted sleeves was developed to reduce pouring on-site and expedite construction. This paper presents a systematic experimental study on the flexural behaviour of beams subjected three-point four-point bending. In total, 11 specimens with different types grouted sleeves, diameters lower transition bar, filler lengths, numbers filler, connect...

Abstract Fully grouted rock bolting is commonly used in roadway reinforcement mining and tunnelling reinforcement.

Grouted Semi-flexible Pavement (GSP) is a novel pavement composed of open-graded asphalt concrete grouted with high-fluidity cement mortar. Due to its excellent load-bearing and anti-rutting performance, it has great potential as overlay surface in road construction. However, the understanding GSP performance remains limited pertinent findings are inconsistent. This article aims provide systema...

in this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. inducedseismic force is one of the most important excitations for the dynamic response of an offshore structure. according to api, seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...

Rehabilitation of a watermain by grouted sliplining is usually carried out when the existing pipe is only partially deteriorated. Although designs that neglect the structural contributions from the existing pipe and the grout are generally conservative, the performance of the rehabilitated pipe needs to be better understood for effective design and management of buried water pipes. Presented in...
